Probably flush the fuel and refill with new fuel, new fuel filter, oil filter with your oil change, probably new plugs too.
Might also benefit from a coolant flush too. Basically just a service and fresh fuel.

Hopefully your brakes haven't seized on though, from my experience Honda brakes like to stick on if left too long.

I was gonna say disconnect the dizzy plug and fuel injector plugs, give it a few cranks for a couple seconds to turn the engine over for it to circulate the oil round so it's not a dry start.

Got an Accord here that hasn't started in years, started straight up like it was yesterday but the brakes had nicely seized so were bit noisy when you get moving, could hear them dragging but eventually free themselves
